So it appears that this would be a situation where you would swap to your DDA's when tank isn't as necessary. But, in practice, what does this mean? For example, from Rykki's Gudie, an unsecured frontier receiver:

When would I be wanting to swap out three Shield Power Relay's for DDA's? Would I want to try and take the first two waves with less tank, put out more drone damage and then swap to the additional relay's before wave 3 and 4?

Also, would you carry a complement of T2 light drones to clear out frigates, or would you try to take them out with your 650mm artillery? Would I want to clear frigates out first, and then focus on Cruisers, then battleships?

I launched an MTU and slapped a remote repair on it, which drew aggro from my drones to me. And I made it through the first wave without an issue. The second wave spawned a little too far from me, and I wasn't able to lock targets, so my drones went on indepentent ops and triggered the third wave too early. I took one too many missles and ate it. But it illustrated an interesting point - with either of these fits, my Myrm is too slow to shake a missile. Each one -will- hit.
